1. Hold the heat source 4 to 5 inches away from the wire. Apply a heat of 275º
F to 300º
F for
about 30 seconds. Rotate the wire while applying the heat so that the heat is evenly distributed.
2. Remove the heat as soon as the tubing conforms to the shape of the wire. Allow the tubing to
cool for at least 30 seconds before handling.
CAUTION
Do not apply heat higher than 300º
F as this may damage the wire. Do not
continue to apply heat after the tubing has shrunk onto the wire. Further
application of heat will not cause additional shrinkage of the tubing.
COMPRESSED AIR/NITROGEN HEATING TOOL
The compressed air/nitrogen heating tool (figure 2-16) is a new tool in the fleet and was designed as
a portable source of heat. This tool is safe for use around fueled aircraft because an open heating element
is not required. The compressed air/nitrogen heating tool can be used on heat-shrinkable tubing.
